オーバートルク防止装九An overtorque prevention device built into a pneumatic rotary tool that uses an air motor built into the tool casing as a drive source to rotate a bit shaft that partially protrudes from the front of the tool casing. A disk is provided on a part of the bit shaft inside the tool casing so that it can rotate integrally with the bit shaft, and is opposed to the front part of the tool casing. The above-mentioned centrifugal valve has a valve body that moves to the disk and a valve spring that elastically urges the valve body inward in the radial direction of the disk, and opens and closes between exhaust holes provided on one side and the other side of the disk. Overtorque prevention device installed on the disk to control the rotation of the bit shaft by guiding part or all of the exhaust from the exhaust side of the air motor through the centrifugal valve to the exhaust hole formed in a part of the front surface.
